The United Farmers of Ontario had affiliated with the CCF but disaffiliated immediately prior to the 1934 election due to a row over suspected Communist infiltration of the party. Accordingly, two UFO nominated candidates, incumbent MLA Farquhar Oliver (Grey South) and Leslie Warner Oke, former MLA for Lambton East, ran as UFO candidates rather than with the CCF. Oliver was re-elected and would subsequently support the Hepburn government.

** 4 Progressives and 1 Liberal-Progressive were elected in 1929. In the 1934 election, Progressive leader Harry Nixon led the party into a coalition with the Liberals under the Liberal-Progressive label. While there are three more Liberal-Progressives in 1934 than in 1929 there was a net loss of one seat if one adds in the Progressives elected in 1929.
